This DC to DC Buck Converter accepts 12V or 24V input and provides a fixed 3.3V output at up to 30A. It is designed to convert higher voltage DC sources to a stable 3.3V rail for 3.3V logic, sensors, and other low voltage loads. The module supports applications in automotive, industrial, and embedded systems where a reliable 3.3V supply is required from common 12V or 24V sources. Key benefits current capability: delivers up to 30A to support multiple 3.3V devices from a single source. Simple compatibility: compatible with both 12V and 24V systems, enabling use in vehicles, machines, and equipment powered by standard DC supplies. Stable 3.3V output: fixed 3.3V regulation for dependable operation of microprocessors, sensors, and communication modules. Efficient stepdown conversion: reduces higher input voltage to 3.3V, helping to minimize heat and maximize performance in compact installations. Easy integration: designed as a compact module suitable for panel mounting or internal enclosure setup, with straightforward wiring to existing 12V/24V circuits. Key attributes Functionality: DC to DC buck converter; steps down from 12V or 24V input to a fixed 3.3V output. Compatibility: suitable for 12V and 24V electrical systems and loads that require 3.3V operation. Size and form: compact module intended for spaceconstrained installations and easy integration into panels or enclosures. Performance: provides up to 30A of current at 3.3V, enabling power for multiple components or subsystems from a single source. Use cases and applications Automotive projects: power 3.3V logic devices, sensors, and small controllers from a vehicle's 12V or 24V electrical system. Industrial control and automation: supply a stable 3.3V rail for controllers, measurement devices, and peripheral modules in control panels or machinery. Embedded and development work: run 3.3V electronics and microcontrollerbased projects from a 12V or 24V supply in hobbyist, educational, or prototyping environments. Notes The converter provides a fixed 3.3V output; the input must be within the specified 12V or 24V range to achieve the rated 3.3V output. Ensure proper wiring and adequate ventilation when operating near the upper end of the current rating to maintain performance and reliability.
